[Narration] In several Central and North Texas lakes,
there lurks a tiny striped invader that is causing problems for motor boats and water
supply systems. [Todd Robinson – Texas Parks & Wildlife Technician]
They have the ability to attach to hard substrates that are upright in water, meaning they could
attach to your boat, they could attach into pipes, onto pumps, any means of water conveyance.
They are a general nuisance. [Narration]
They’re called zebra mussels and Texas Parks and Wildlife is trying to stop the spread
of this invasive species with a new statewide rule requiring boaters to drain all water
from their boats every time they leave a public lake, river or creek. This rule will keep
boaters from unknowingly transporting the small but destructive invasive across the
state. Adult Zebra mussels grow to just 1.5 inches and the larvae are invisible to the
naked eye. They can hid e in water left in your boat such as live-wells, bilges and bait
buckets. [Todd]
We urge them to go ahead and have the maintenance staff at the marina that they’re at go ahead
and pressure wash the boat to remove them off right there at the lake. [Narration]
Zebra mussels originated from Eurasia and are believed to have been transported in ballast
water from ships into the Great Lakes. They entered Texas in 2009 and are now in several
Texas lakes and rivers and threatening to spread throughout the state. With the summer
boating season under way, Texas Parks and Wildlife is ramping up awareness. [Todd]
Buoys at 17 different marinas and we have signage at all the access points. We have
billboards out on the highway, and at all the gas stations, we have pump toppers.” ((spray painting)) [Todd]
We are putting 6ft by 8ft stencils at several locations. [Todd]
They are here and they’re not going anywhere. There’s no way to totally eradicate them.
At this point we’re just wanting to prevent their spread throughout the rest of Texas. [Narration]
For Texas Parks and Wildlife, this is Karen Loke.
